I see alot of people who I assume take articles in their native language, and then Google translate it into english so that the Cheetah bot don't catch them plagiarizing.
Some guy posted an interesting article that I commented on since it's related to my cultural heritage, and when we started conversing, the guys native was CLEARLY not english and he copied and pasted the content from somewhere else. I looked at his profile and he's posting 10 articles an hour using Google translate.
